Thermodynamic Model of Silicon Smelting in Ore-Smelting Furnaces
Materials Science Forum, 2020Silicon production by silica-containing raw material reduction by carbon in ore-smelting furnaces (OSF) is a complex pyro-metallurgic process. Silicon is produced in a system consisting of charge, furnace electrodes, air, melt, slag, and gases at temperatures above 2000°C, which generates silicon monoxide and carbide unavoidably.

Abstract— Ureilites containing homogeneous Fo76 olivine cores in intimate co‐existence with graphite must have recrystallized at pressures of at least ∼100 bars to suppress smelting of the fayalite component of the olivine to Fe metal. Smelting of olivine and pyroxene‐saturated magmatic liquids produces orthopyroxene‐without‐olivine crystalline ...

Modern Continuous Smelting and Converting By Bath Smelting Technology
Canadian Metallurgical Quarterly, 2001AbstractThroughout much of the twentieth century, bath smelting technologies have been important for the production and refining of ferrous and non-ferrous metals, a trend which is expected to continue into the next century. This situation is no less true than with copper pyrometallurgy where such primary smelting and converting technologies now ...
